(150 ma for the MicroReader, 1.5 A for the RFM-104B and 2A for the RFM- 007B/8B) The power supply must be located close to the reader (avoid long DC supply lines). Route power and control lines separately. Power and antenna cables must be routed separately. 3/28/2008 TI Proprietary Information 9

26 Standard Antennas G04E G01E G02E S01C 3/28/2008 TI Proprietary Information 26

27 Standard Antennas The G01E and G02E antennas come with 1m (39 ) cables. These can be extended using low resistance cable (e.g. 2.5 mm Oxygen Free Hi-Fi cable) by a further 2m without significant reduction in performance and they should still be capable of being tuned to resonance. The leads of these cables are made from Litze wire to achieve maximum performance. This wire comprises 120 individually insulated (lacquered) wires and should the connector break off, the lacquer should be removed by heating before sweating on a new terminal. (crimping on a terminal will result in low performance because of the high impedance) The G04E antenna has a slightly lower Inductance (26 µh) to allow you to fit a 4m long lead (of low resistance wire) and still be within tuning range. We do not advise extending the antenna cable more than necessary, as reduced performance will result from the increased resistance, the extra inductance could prevent successful tuning and the antenna will be more susceptible to noise 3/28/2008 TI Proprietary Information 27

31 Antenna Tuning The Antenna and its cable are all part of a INDUCTANCE/ CAPACITANCE circuit that has to be tuned to resonance to get best performance. The formula for this circuit is: ƒ (res) = 1 2π LC INDUCTANCE CAPACITANCE This can be done by changing the Inductance (ferrite cored inductor) or Changing the Capacitance (capacitance jumpers ) Note: Changing the antenna cable length or metal near the antenna will also change the tuning 3/28/2008 TI Proprietary Information 31
